for gear shit: levers of motor vehicles. and i the invention has lorits object to provide mechanism in connection with levers of the character specified. for preventing unauthorized use of the vehicle, when desired, b ki i im ossible for any one to use the lever to operate the transmission.

the lower sec- Fig. 6 is a sectional view at right angles to Figs. '1 and 2 of the upper end oi the lower section, with parts separated,

Fig. 7 is a plan view of the lower section.

In the present embodiment of the invention the improved lever comprises an upper section 1, and a lower section which are connected together at their adjacent ends by a ball and socket joint 3-l, the section 1 carrying the ball, while the section 2 carries the socket. The socket *2 is sectional, consisting of the portion rigid with the section 2, and a portion 5 which is detachable from the section 2, and is connected thereto by means of bolts and nuts 6, which pass through registering openings in the removable portion and in the fixed portion of the socket.

The lower end of the section and the ball 3 are cored axially as shown at 7 and within this cored opening there is arranged a bolt 8 which is movable longitudinally of the upper section. Referring to Figs. 1 and 2, it will be seen that the upper section of the lever consists of two portions extending at Specification of Letters Patent.

an obtuse angle witl respect to each other. and at the junction of the said portions therc is provided a laterally opening casing J. which carries within the same a lock it) of an usual or desired construction. as for instance a pin or cylinder lock. The releasable portion of this lock is pivotally con nected in an usual or desired manner with the bolt b. 28 indicated at 11. the arrange.- ment being such that when the lock is op erated in one direction by'thc ke v the bolt will be withdrawn into the axial opening of the upper section, and with its lower end fiush with the lower end of the upper sec tion, as indicated in Fig. 2. while when the lock is turned in the opposite direction the bolt will be extended as shown in Fig. 1.

The lower section 2 has an axial recess 1% for engagement by the lower end oi the bolt when the bolt is extended. to lock the sections rigidly together, so that the lever niay be operated as a whole from the grip to control the transmission. Preferably the bolt and the openings therefor are polygonal in cross section to prevent rotation of the bol although it is obvious that this is not essential and in practice there is provided an opening 13 leading down 'ardly and outwardly from the bottom of the recess 12, to permit the escape of oil. dirt and the like. The ball and socket joint is mounted in the usual zone shaped bearing H inthe foot board, and the socket which is substantially spherical serves as the fulcrum upon which the lever moves.

1 claim: 7

A gear shift lever having a fulcrum ball intermediate its ends, and being divided into sections at the ball, one section having a socket and the other a ball received within the socket, said socket forming the fulcrum of the lever, and means controllable by a key. for locking the sections in a predetermined position or for releasing the sections, said means comprising a bolt mounted to move axially of the section having the ball, the socket section having an axial recess for engagement by the. bolt, and a. key controllei'l lock connected with the bolt for controlling the same.
